Harvesting will continue to be considered as a <br />management option if grazing is not implemented in any given year. Peabody does not own <br />or run its own livestock herds, thus, it must rely on local operators for livestock to <br />graze the pastures. A rotation grazing system will be used when grazing of the irrigated <br />pasture type occurs. When livestock grazing cannot be implemented, harvesting will be <br />used to simulate grazing. Hayland harvests will be by equipment only. All species in <br />Mixes #5, #6 and #7 are capable of producing high quality hay, though birdsfoot trefoil <br />may produce 20 -50 percent less than alfalfa (Heath et al. 1985). Aftermath grazing (i.e., <br />grazing after the last hay cutting) will not be carried out on reclaimed irrigated <br />haylands if the Last cutting is near the end of the growing season. Harvested hay will be <br />removed from the fields as rapidly as hay quality and weather conditions permit. <br />The following describes the general management considerations to be applied when grazing <br />or harvesting the irrigated pasture and hayland types: <br />Grazing - Grazing will not start until the forage has achieved an 8 -14 inch height. <br />- Grazed stubble height should be approximately 6 inches and never less than 4 <br />inches. <br />- Allowance should be made for a 21 -30 day recovery period, never greater than 30 <br />days. <br />- Allow for 6-8 inch fall regrowth before first frost. <br />- Periodically clip uneven growth to reduce spot grazing. <br />- If irrigation results in excessively wet conditions, defer grazing. <br />- The above management considerations are for maximum production and maintenance <br />of a productive and vigorous stand. <br />Hay (Harvest) - Cut hay when grass is in the boot stage and the legume is in the early <br />bloom. <br />- Minimum cutting height is 3 inches. <br />- The last cutting should allow for a 2 -4 week regrowth period before the <br />first frost, which occurs within the first two weeks of October. <br />- Depending on length of season, up to 3 cuttings of hay may be taken. <br />Revegetation Methods - Dryland Pasture. The dryland pasture type will be established in <br />areas which were previously sagebrush rangeland on Travessilla -Pinon soils (Map Unit 1E in <br />22 -25 Revised 07/25/91 <br />
